PROBLEM TO BE SOLVED: To provide a biological information measuring device in which vibration generated from a vibrating member is directly transmitted to a terminal mounting surface, so that the entire terminal mounting surface emits sound waves. SOLUTION: In a biological information measuring device for performing acoustic wave communication with an external terminal (41) equipped with a microphone (43), a biological information measuring device (11) is disposed inside a housing (21) and a living body. A measurement circuit (73) for measuring information, a modulation circuit (78) for converting the measured biological information into a sound wave signal, and a vibrating member (42) for vibrating based on the sound wave signal transmitted from the modulation circuit. The housing has a terminal mounting surface (40) on which the terminal is mounted, and the vibrating member and the terminal mounting surface contact each other so that the vibration generated by the vibrating member is transmitted to the terminal mounting surface. doing.
